Im going to guess reactivity with elements in the air, heat, I think (not
positive) some rubber compounds just decompose over time.

I sort of succeeded, except for the part that the sealant from the

Messy.
I'm not sure why some of the early Connor hard drives did this, but it
appears
that the rubber seal/o-ring they used breaks down and turns to goo.
It is an extremely common problem with their 20MB and 40MB IDE drives, but
I've not seen this happen with Connor drives over about 80MB. This seems to
be very similar to what we see with a lot of the self-stick rubber feet on
modems, external drives, and other peripheral devices turning to goo.
